What's new

New Ford Duallys are 6+ months out?

It happens just often enough that the dealerships use that to deny warranty claims all the time. CP4’s eating themselves is a known problem but even if it was just a run of the mill CP4 come apart. Dealership has to be the only one to work on it for it to be under warranty. They’ll say you put DEF in the diesel tank and deny the warranty.

It would be nice if warranty would cover it, but I also think it shouldn't be used when it was his own negligent that caused the problem. But I can guarantee he won't do that again. I'm also guessing the dealership will replace everything, just because they can, he won't know what was actually damaged. Last I heard, it was going to be over 12 grand to fix it.

They also like to tell you it was "bad fuel" and that water killed the CP4 and they are not going to warranty it.

So you are telling me your fuel filtering system isn't adequate? :crickets:

Some day I can see all us ford CP4 truck owners getting a check in the mail. Ford is running out of excuses faster than those pumps are blowing up and every other manufacturer stepping away from the CP4 doesn't look good for Ford either. Eventually it's going to catch up to them.

He should be able to put on his insurance...
 
On the duel fuel tanks on the 450. One is between the frame rails at the very back, one outside the rail on the drivers side. They fill up separately. The main fuel gauge on the dash shows combined fuel. You can cycle through the dash stuff and see a gauge for each individual tank. It seems to pull from both tanks, but so far it only has a couple hundred miles on it.
 
Ok, I'll tell on myself for being a dumbass. I put 5 gallons of DEF in my fuel tank a few years ago. I was in a hurry to get out of town hooking up the trailer, loading stuff and on the phone. Realized it before starting the truck. Grabbed my Milwaukee transfer pump and siphoned it all out. Added another 10 gallons and repeated the process. Truck still ran perfect 8 months later when I traded it in. The process did end up smoking the Milwaukee transfer pump.

Woo dodged a bullet there.

I always thought If I ever dumbed like that I'd put a self tapper through the lowest point :homer:

They didn't do shit for all the people that bought 6.0s and 6.4s that blew up on them, and it was well documented manufacturing flaws in those.

They're not gonna do shit for the CP4 owners, either. And people will still buy them by the thousands.
 
Did gm overdrive the cp4 like ram? Seems like they were way worse in the ram and GM, hence them going away from them.

I try not to be biased, but I really don't see them failing as often as people say. 1 in a porta potty truck, driven by idiots and one in a 220k mile truck that couldn't remember when they last changed the fuel filters. Every place I've worked since the 6.7 psd was released has used them. Not saying I'm going to know every detail of every truck, but usually if someone shows up in a different truck and it's $10k+ to fix, you'll hear about it.

The same porta potty driver said his truck was leaking. Pulled into the shop and there is a hole knocked in to the cast on the massive Dana rear axle (m300?) claims he didn't hit anything :lmao:

I have 3 6.7 trucks. One has the full CP4 failure contaminated lines injectors etc. in my circle there’s 7 6.7 psd’s so that would make 1 in 7 CP4 junk outs in my peripheral. For now, that number can only go up not down
 
On a different note, anyone put closed end lug nuts on their dually?

I'm trying to clean up the ratty steel wheels on mine and not sure the chrome caps are it :laughing:

Ignore the broken stud, replacing those now:homer:

That's a tough comparison since I know you bought that truck from auction because of that failure and probably don't know the history of how it was maintained or if it was due to death in the fuel Etc?

How many cp4 trucks does your company have running around every day without issues though?

Just to be clear I'm not trying to argue and tell everybody they're wrong and that they don't fail more of just playing Devil's Advocate. I trust my truck as much as anything however I did put the dpk on it just in case

Hundreds and most of them with no issues, way most of them with no CP4 issues

And I only mention it because I don’t want the bad karma of pretending it’s not a potential ticking time bomb. I just want to acknowledge that it’s a real thing across the board. I have friends who had Duramax’s that did it. One when the CP4 did its thing ruined the whole engine, broken piston scarred cylinder the whole 9 yards. GM had a class action suit and both those guys got cash payout to have their trucks fixed. They both did CP3 conversions.

Good call, maybe I should just shut up :laughing:

From what I've read, the ford doesn't use the same Cp4 as ram and gm. I recently read that ram was over driving the cp4 which may have lead to it being less reliable. No idea on gm.

To me it sounds like it's not so much that they are all failing, it's that when one does fail, ford is really trying to get out of it and people are justifiably throwing fits over a $10k+ bill on a $80k+ truck that's supposed to be under warranty. With all the sensors and gizmos on these trucks, it should either shut off or be able to filter better before the fuel pump fails.
 
If your 6.7 truck ever pops up a code for low rail pressure even it the CEL goes right back out change the CP4. From everything I've read and watched online recently about the Ford CP4 tells you that is usually the first sign it's going to shit the bed. Had I known that a year or so ago when my service truck threw that code temporarily I would have caught it before it blew up.

I remember the day clearly. I left the shop at 8am to head to El Paso and as soon as I pulled out of the gate and hit the gas it hesitated for a split second and the CEL light came on so I drove to the Ford dealer down the street and had the service guy pull the code to see if it was something that would prevent me from making the trip. He showed me the code for low rail pressure, cleared it and then went for a quick ride with me to see if I could duplicate it and it didn't happen again so he said it was probablybecause it was still cold when i left. Drove it several thousand miles after that over a year or more without issue* and then one day it blew up.

Hindsight is 20/20 but maybe sombody else will read this and save theirs before the pump junks itself and the fuel system.
 
The * I put next to "without issue" was supposed to have an explanation below it.

*Truck slowly lost power over the next year and it wouldn't build as much boost as it did previously. It got waaaaay slow in the end.
 
That reminds me that my FIL, drove like 40-50 miles after his threw a low rail pressure code(iirc that was the code). Wonder if he had stopped immediately and had it towed, would it not have been a full fuel system replacement?
 
Went to one of the local ford places today to look at a truck. They have two STXs with the 6.8, the remaining F250/350s are lariat, platinum, or king ranch packages with a mix of the diesel engine options. Drove a sport packaged SO diesel. It was nice, but I’m not high on the moon roof or a bunch of the other things it had added on.

I’ve got bigger problems if he speaks to me from the great beyond.

I really want to find a 7.3 truck, but they haven’t been on the lot locally.

I also went and looked at a Tundra because the dealers are close. Wasn’t overly impressed with them, but I figured that would be the case.

Just order one, dealers always tag on a lot of gay packages that you don’t want like a sunroof.

I think the 7.3 may be xlt or lariat and up now, probably why your not seeing them in xl and stx trim levels.
 
I’m betting it was 3.73. I’ve had a hard enough time finding a 7.3 locally. The 4.30s seem even harder to find.
It may be getting a little late in the model year for ordering one, but it’s really the only way to go. Unless you’re looking for a Lariat Tremor or one of the other three configurations they keep on the lots.
